Air inlet structure, air conditioner indoor unit and air conditioner

Abstract

The invention provides an air inlet structure, an air conditioner indoor unit and an air conditioner. The air inlet structure comprises an air inlet grille and an air inlet baffle, the air inlet grille comprises at least one grille strips, and an air inlet of the air conditioner is formed in the positions of the grille strips; and one end of the air inlet baffle is connected to the air inlet grille, and the other end of the air inlet baffle can movably open or close the air inlet, so that the air inlet is closed when the air conditioner is in a non-running state. According to the structure that the air inlet baffle is additionally arranged at the air inlet grille, the air inlet can be opened or closed through movement of the air inlet baffle, particularly, the air inlet is closed when theair conditioner is in a non-running state, an effective dustproof effect can be achieved in the non-running state of the air conditioner, dust is prevented from entering the air conditioner, resistance is prevented from being increased, so that, the air outlet effect and the heat exchange effect are effectively improved, and the service life of the air conditioner is prolonged.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air inlet structure, an air conditioner indoor unit and an air conditioner. Background technique [0002] With the development of society and the improvement of people's living standards, air conditioners have been widely used in people's daily life. At present, the inner unit of the air conditioner on the market is mainly composed of the following parts, the panel body parts, the panel parts, the electrical box parts, the evaporator parts and the wind deflector mechanism. Generally speaking, the air conditioner at least includes the air inlet structure and the air outlet structure , when the air conditioner is running, the indoor air enters from the air inlet of the air conditioner, passes through the evaporator components, and blows out from the air outlet. The suction grille components include the suction grille and the suction plate. The suction grille is detacha...

AI Technical Summary

Problems solved by technology

The suction grille components include the suction grille and the suction plate. The suction grille is detachably installed at the air inlet. The air inlet is normally open. When the air conditioner is not running, dust will enter the interior of the air conditioner, causing Increased resistance, wind effect and heat transfer effect will be significantly reduced, affecting the service life of the air conditioner

In addition, the air inlet structure of the existing model mainly includes a cover plate, a grille, an air intake baffle, and a drive box component, wherein the cover plate and the grille are snapped together, and there are a large number of snaps, resulting in low assembly efficiency. Fixed bugs like unreliability

Moreover, the mounting direction of the rotating shaft of the pressure plate at both ends of the existing model is perpendicular to the direction of the rotating shaft of the baffle, resulting in the interference of the assembly stroke during the installation of the baffle, which is not convenient for assembly in the production process.

[0003] Since the air inlet structure of the air conditioner in the prior art belongs to the normally open type, dust will enter the interior of the air conditioner when the air conditioner is not in operation, resulting in increased resistance, significantly reduced air outlet effect and heat exchange effect, affecting the use of the air conditioner life; and existing from top to bottom (perpendicular to the direction of the surface of the air inlet) to install the pressing plate rotating shaft, there will be technical problems such as assembly stroke interference problems in the assembly process, so the present invention researches and designs an air inlet structure , air conditioner indoor unit and air conditioner
